Alright. That is surprising to me.
If I were to do analysis, I would follow equation 44-49 in the datasheet.
If you provide me with all applicable variables, I can verify your calculations.
Please share the calculations so far.
We can then double…
Part Number: TPS54540 I am using TPS54540DDA in my design. I am giving an input of 12 V (VCC_SELECTED) and taking an output of 5 V (VCC_5_BB).
But under load condition TPS54540 is not able to support more than 0.5 A current. When i am bypassing TPS54540…

Hi Team,
My customer use TPS54540 as the first power stage in automotive. change 12V to 5V.
However, met the following problem: ACC ignition power does not start. It means it can't work in STAR-STOP when Vin drop to 8V.
When…
Part Number: TPS54540-Q1 Dear support member,
I have a question.
My customer used TPS54540-Q1. Currently in mass production.
There was a phenomenon that the duty of the switching voltage waveform changes.
There is a question as to whether the…
Part Number: TPS54540 A customer of mine would like to know if and how we test the Overvoltage Protection feature of the TPS54540. Can someone help me with this?

Part Number: TPS54540 Hello, our customer is using our TPS54540 and has a question below, can you assist?
"I was reading the datasheet, and was surprised that there is not a resistor value in Table 3 for a 12V output. Should I replace both R5 and…
Hello, I found other documentation of TPS54540 and noise suppression www.ti.com.cn/.../slvu973.pdf
In this documentation, they add snubber in SW pin.
In my precedent post, i haven't measures the noise in SW pin but in output after the inductor.
I had…
Part Number: TPS54540 according to the spec, if the EN pin is pulled lower than 1.2V
the switcher is turned off
i have turn off my tps54540 dda part with the EN pin below 0.6v
but i still see at least 1.5v at the switcher output
why is that so…
